The client will send a dynamic dns request directly to the SOA to update the A and PTR records. Method 3: Client updates the PTR record directly. Macs do not register using this method.īoth method 1 and method 2 are discussed here (WS.10).aspx.
The request is sent with the hostname to be registered, and the DHCP server sends back the result. With this method, when the DCHP server gives out an address to the client, the DHCP server registers the PTR record with the DNS server.ĭHCP has an option that the client can send to the DHCP server when making a request that asks the DHCP server to register the hostname on its behalf. Method 1: DHCP Server Registers all clients. Even within the DHCP server registering the reverse, it can be done at least 3 ways: Some have the DHCP server register the PTR or have it register both the A and PTR.
Some AD infrastructures don't allow reverse, don't allow A or PTR, and allow both. The AD plugin attempts to register both the A and PTR record directly. Net -d 2 -n mac -W -P ads dns registerĭNS updating is done a ton of different ways depending on the environment and whether it is the A or PTR record. Run it with -d 2 to see the errors (or crank it up to 255 to see lots of details): So if your computer account in AD is called mac$ and your domain is, it would be: Net -n computername -W domain.name -P ads dns register 2010 - ):ĭynamic DNS resolution is done at a network event via: Timothy Perfitt wrote (MacEnterprise mailing list, Mar. Has anyone come across this before? Will an Apple Mac change it's hostname based on a DHCP lease from a Windows server? I've been through DHCP and DNS and it's all correct except the reverse lookup address entry is for the incorrect hostname. I wonder if this is what has been happening to me all these years- share name and hostname is different, and somehow the hostname on the Mac is being changed when it picks up a new lease? The technician changed the hostname and the software started working again. HOWEVER, the technician then ran hostname in terminal, and sure enough this new names turns up. Checked the sharing tab on the Mac, and the name is still what I set it to. I was troubleshooting an ongoing issue with our cloud backup software, and today the Mac wasn't listed in the software, just a hostname I didn't recognise. We've since bought new Macs and AD joined them from day one, and we've not seen the issue since until day. It did it with our old Macs in my current jobs, and I just ended up ignoring it as it wasn't causing major problems.

I think what has happened is when a PC lease has expired in DHCP, the Mac has picked up the IP address and then it's shown as different in Sophos. You get multiple entries in DHCP and DNS with different IP addresses.
I end up with duplicates in Sophos, one for the PC and one for the Mac that has 'stolen' the hostname. I set a name for the Mac in System Preferences under the sharing tab, but after a few months I notice in Sophos Enterprise Console the names under the Apple Macs folder are all wrong- they are names of random PC's on my network, and the Mac names have all gone. I've seen this issue a few times in this job and my last job.
